FRED SCHMIDT, OF OHICAGD, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNEASSIGN- MENTS, 'IO MAJOR ENGINEERING CORFORATION, A CORPORATION, OFILLINOIS.

INTERNAL-COMBUSTIN ENGINE.

Application mea Mai-'h 17, 1921. serial Np. 453,109.

To all whom 'it may concern- Be it known that I, FRED SCHMIDT, a citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and use-` ful Improvementsin Intsmal-Combustion1 Engines, of which the following is aspecitication.

The invention relates to improvements in internal combustion engines oiEthe turbine type and associated air compressors.

An object is to provide a turbine engine having a rotor arranged to bedriven by impact of the exploding charges projected from a contiguouscombustion chamber.

Another object is to provide a structure having a combustion chamber inwhich an explosion takes place and in which the valve is automaticallyopened by the effect of the explosion to permit the products ofcombustion to be projected against the peripheral surfaces of anassociated rotor.

Another object is to provide, in an engine of the character described, acasing containing a combustion chamber having an admis-k sion` valvewhich automatically opens as a result of the pressure of the charge toadmit the charge into the combustion chamber and another valve thatautomatically opens by the eii'ect produced by the explosion, to permitthe products of combustion to strike the peripheral surfaces of therotor at suitable intervals to drive the same.

Another object is to provide means for introducing steam or vapor intothe eX- ploded charge after it leaves the combustion `chamber and beforeit strikes the rotor.

Other, further and more specific objects of the invention will becomereadily apparent, to persons skilled in the art, from a consideration ofthe accompanying drawings, wherein z- I `ig. 1 shows a central sectionalview of one of the large casings, or bottles, containing a combustionchamber, within which the explosions occur. K

Fig. 2 is a section taken on l1ne2-2 of Fig. l.

In all the views the same reference characters are employed to indicatesimilar parts.

I The casing is provided with a lange 82, having holes 83 thru which capscrews Bet may be inserted to secure the casing to the fraise of theengine The Casing 0r bottle 75 is provided with a head 85 screw threadedas at 86 for insertion in the end of the casing. The. head Sois alsoprovided v for a piston head S9 `which is the terminal end of the tube87 and the head S9 moves. freely inthe bore 88. The valve is held closedby an open helical spring 91, the strength of which may beadjusted bythc screw plug 94A. f

The piston 89, of the valve 79, is larger than the tubular portion 90 ofthe valve, and at intervals around the bore 88 are a series ofperforations `or holes 93 openingV romthe interiorof the bore to theinterior or the bottle or the combustion chamber 76.

A spark plug 92, threaded into the casing 7 5, near the port 78 thruwhich the products of combustion are discharged upon the occasion of anexplosion of the combustion provided with terminals 9 5. The casing 75is provided with a hub 96'which is internally screw threaded, as at 97and into which a plug 98 is screwed carrying a check valve 99, normallyclosed by the spring 100.

The fuel charges consisting of the proper admixture of air and suitablequantity of gasoline vapor comes thru the pipe 101 from the compressorsand is delivered into the combustion chamber 7 6 by thev self-openingpuppet valve 99.

The spring 100 is set so that when the pres sure of the charge to beinjected into the combustion chamber 7 6 is suliicient to overcome theresistance ofthe spring, the chamber is filledwith an explosive mixtureunder pressure. Just at the time when the pressure is at maximum value aspark is produced at the terminals 95 of the spark plug 92, whereupon anexplosion will take place in the chamber 7 6. The eect of the explosionis to open the valve 79 by the pressure applied to the piston 89 oit thevalve 79 thru the openings 93. Immediately upon the opening of the valve79, the products of combustion will pass out with considerable force,thru the nozzle 89, and iinpinge upon the cups of the rotor, therebycausing the rotor to revolve at high velocity. Y

A Water supply pipe 102 leads from a suitable ysource of supply andconnected to the valve 103 which may beopened, to a greater orlessextent, by rotating'the handle (itt chamber, is screwed into the casingand is and at high velocity, it produces a vacuum eect in the tube 90 ofthevalvefQ `and causes Water tobe drawn into the tube Which is convertedinto steam" bythe hot lsurfaces of thetube 90 and lwhich goes outWiththe f next-charge that leaves the combustion chamber 76. '.'By thismeans Wateror steam which is more ponderable than the gases ofexplosionis carried with 'forcible effect-"against the peripheral surface of the.rotor.

The power thus producedis much :greater than -it'otherwise Vwould *beWit-houtthe lassistance of "thewvaten The Water furthermore has theeffect of keeping thecombustion-casing frelatively cool so as to preventspontaneousl explosion. "While the" engine Will-*run Withffair eliciencyWithout the Water `for a protracted period of time Without dangerousheating, it `is believed that the Water 'contributes tojproduce a higherefiiclency, its expansion vinto steam contributl'ingto the force of theimpact.

I-Iavilrg described 'my invention VWhat-'I claim .as tnew and Adesirentosecure by'l Letters Patent, is:-

lA vernnbu-'stion chamber agnd nozzle for turbinegas engines comprisinga b0ttle-like Within the casing and' a' pipe Within the tubular valve,whereby tofintro'duce Water therein by the suction 'effect 'produced -bythe heated gases thru saidfport.
